Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Multiple fixes address missing ACL rules being implicitly allowed, enabling privilege escalation. The pattern of deny-by-default is applied inconsistently across roles and resources.
Path Traversal: Path canonicalization and separator handling are repeatedly fixed, indicating a systemic weakness in path validation that allows escaping the intended directory. Sibling code paths may miss the same canonicalization.
Auth Bypass: GraphQL resolvers for products and categories lacked permission filtering, exposing restricted data. Fixes added context-based checks, but sibling resolvers may still miss these.
